About Bitumen Extractor Electrically Operated
Bitumen Extractor Electrically Operated is a precision laboratory instrument used for determining the percentage of bitumen in bituminous paving mixtures and road samples. The test is carried out by dissolving bitumen in a solvent and separating it from aggregates through centrifugal action.
The apparatus consists of a removable aluminum rotor bowl, cylindrical housing, vertical shaft, and electric motor drive system. The electrically operated model is equipped with a variable speed control mechanism, enabling smooth operation within a standard speed range of 24003600 RPM for accurate extraction.
This equipment is widely used in civil engineering laboratories, highway construction projects, and quality control labs for asphalt mix analysis.

Working Principle
The bituminous sample is mixed with a solvent and placed in the rotor bowl. When the machine rotates at high speed, the bitumen dissolves and is separated from aggregates by centrifugal force, and the extracted solution is collected for analysis.
Efficient Bitumen ExtractionThis extractor harnesses a belt-driven, 0.25 HP electric motor to provide quick and accurate bitumen separation from asphalt mixtures. Its stainless steel removable bowl and powder-coated finish ensure durability even in demanding environments. Operating at ambient to 50C, it produces minimal noise and is easy to install anywhere with standard 220V AC power supply.
Enhanced Safety and Convenience FeaturesSafety is addressed through a secure locking arrangement and safety cover, while its tabletop design and inclusion of key accessories like an instruction manual make setup and day-to-day operation straightforward. Removable bowls support fast sample turnaround, and the rugged frame protects against frequent use in busy labs.
FAQ's of Bitumen Extractor Electrically Operated:
Q: How is the bitumen extraction process carried out using this electrically operated extractor?
A: Bitumen extraction is performed by placing the sample into the stainless steel removable bowl, adding a compatible solvent (such as trichloroethylene), and securing the safety cover. The centrifuge then operates via electric motor, spinning at standard speed to separate bitumen from aggregates effectively within 5-10 minutes.
Q: What safety features are incorporated in this extractor?
A: The extractor is equipped with a robust locking arrangement and a safety cover, ensuring secure operation by preventing access during use. The heavy metal stand frame and powder-coated finish add durability and user protection.
Q: When should the stainless steel bowl and filter paper be replaced?
A: The removable stainless steel bowl and filter paper should be inspected regularly. Replace the bowl if you notice significant wear or damage, and change the filter paper after each extraction cycle or when it becomes clogged to maintain high extraction accuracy.
Q: Where is this Bitumen Extractor suitable for use?
A: This extractor is ideal for road construction laboratories, quality control departments, research centers, and any facility involved in the analysis of asphaltic paving mixtures. Its compact tabletop design (410 mm x 410 mm x 600 mm) makes it convenient for various workspaces.
Q: What are the main benefits of using this bitumen extractor?
A: Key advantages include high extraction accuracy, rapid processing time per batch, compatibility with common solvents, rugged construction for long life, and safety-focused features. The removable bowl and efficient extraction process maximize productivity and ease of maintenance.
Q: How do I operate and control the machine during extraction?
A: Operation is simple: place your prepared sample in the bowl, add solvent, secure the safety cover, and use the electrical switch control to start and stop the centrifuge. The analog meter and standard pressure gauge assist in monitoring the process for optimal results.
